Re: [Gretl-users] Conversion from a Formula to a Description

In the Gretl GUI one can define a new variable by ADD -> DEFINE

This works quite nicely, and I can define something like y=cos(2*pi*x/5) and
use it in a regression. In addition, I can right-click on y, select EDIT
ATTRIBUTES, and edit the formula, changing it to y=cos(2*pi*x/10) for example.
In general, this is a very useful feature of Gretl.
However, if I save the file and reload it the "formula" becomes a
"description" in the EDIT ATTRIBUTES window. This means I can no longer edit
the formula. Is there a way to retain the ability to edit the formula after
saving a session?
No, the variable then becomes part of your dataset. But you can
easily redefine the variable if you want, by doing Add/Define new
variable and re-using the old name.
